When a user views a memo containing such an image, their browser automatically fetches the image URL without explicit user consent or interaction beyond viewing the memo. This can be exploited by an attacker to disclose the viewing user's IP address, browser User-Agent string, and potentially other request-specific information to the attacker-controlled server, leading to information disclosure and user tracking.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-200"],"references":["https://github.com/fai1424/Vulnerability-Research/tree/main/CVE-2025-50738","https://github.com/usememos/memos","https://github.com/usememos/memos/issues/4707#issuecomment-2898504237"],"products":["usememos:memos"],"source":"nvd","synced_at":"2026-10-19T22:05:46.678065081+00:00"},"epss":{"cve":"CVE-2025-50738","score":0.02423,"percentile":0.84191,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-hfcf-79gh-f3jc","url":"https://osv.dev/vulnerability/GHSA-hfcf-79gh-f3jc","summary":"Memos has Cross-Site Scripting (XSS) Vulnerability in Image URLs","modified":"2025-08-22T21:08:25Z","packages":[{"ecosystem":"Go","name":"github.com/usememos/memos","purl":"pkg:golang/github.com/usememos/memos","ranges":["<0.24.4"],"fixed":["0.24.4"]}]},{"id":"GO-2025-3831","url":"https://osv.dev/vulnerability/GO-2025-3831","summary":"Memos has Cross-Site Scripting (XSS) Vulnerability in Image URLs in github.com/usememos/memos","modified":"2026-03-03T04:57:22.791377Z","packages":[{"ecosystem":"Go","name":"github.com/usememos/memos","purl":"pkg:golang/github.com/usememos/memos","ranges":["<0.24.4"],"fixed":["0.24.4"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
